Replace Interior Incandescent Lights with LED's and Re-Wire Galley Light

[RF_Burns]

Was there a reason you could not just reverse the connections of the shell and pin wires coming from the lamp? I've replaced the OEM lamp so I can't
exam its wiring.

My new lamp has a simple ON/OFF switch with both lamps wired in parallel. So I wired the power as normal but through a 5 Amp diode. I wired the
power from the switch by the door through another diode, but to the lamp side of the switch. This lets me turn ON the lamp from the door or the light
itself. Both switches must be OFF for the light to turn OFF.

The diodes just isolate the power feeds from two different fuses.

Clark,

Your mis-understanding the switch is very understandable....

That switch is not DPDT in the normal consensus. It is a three position two pole switch and it is set up to allow one to select between one or both
bulbs. On boats (and one GMC). Mine was set up so you can bring up one bulb that is red for doing things night driving or just one bulb for normal
owners.

I really does not matter what you do as long as you document it in the coach's paper work.

And yes, I have run into reverse polarity on many of the coach's lighting fixtures - Inside and out - My DOT lights were all backward. After the
first failure, I wired all the rest with the system hot.
